Tests:

Switch
var animal = ["dog", "cat", "cattle", "cheetah"][Math.floor(Math.random() * 4)] function test(animal) { switch(animal){ case 'cat': return 'Kitten' case 'cattle': return 'Calf' case 'cheetah': return 'Cub' case 'dog': return 'Pup' default: return "I don't know that" } } console.log(test(animal))
Object Literal
var animal = ["dog", "cat", "cattle", "cheetah"][Math.floor(Math.random() * 4)] function test(animal) { var babyAnimal = { cat:'Kitten', cattle:'Calf', cheetah:'Cub', dog:'Pup' } return babyAnimal[animal] ?? "I don't know that" } console.log(test(animal))
If Else
var animal = ["dog", "cat", "cattle", "cheetah"][Math.floor(Math.random() * 4)] function test(animal) { if(animal==='cat'){ return 'Kitten' } else if(animal=='cattle'){ return 'Calf' } else if(animal==='cheetah'){ return 'Cub'; } else if(animal==='dog'){ return 'Pup'; } return "I don't know that" } console.log(test(animal))
Object Literal defined outside function
var animal = ["dog", "cat", "cattle", "cheetah"][Math.floor(Math.random() * 4)] function test(animal) { return babyAnimal2[animal] ?? "I don't know that" } console.log(test(animal))
